Configuring loop protection
Loop protection provides protection against loops by transmitting loop protocol packets out of ports
on which loop protection has been enabled. When the switch sends out a loop protocol packet
and then receives the same packet on a port that has a receiver-action of send-disable
configured, it shuts down the port from which the packet was sent.
